Description of the invention (]) The technical field to which the present invention belongs (please read the precautions on the back before filling this page) The present invention relates to an output control device for a semiconductor device for power use. Conventional techniques are included in the output circuits of motors, regulators, and other drive circuits or power circuits to protect circuit elements from overcurrent, or to control the output current so that it does not exceed a predetermined value. A blocking circuit for blocking the output current. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 13 is a conventional example of one of the interrupted circuits. The output transistor 1 is a transistor for driving the load 3. A resistor 101 for current detection is connected to the output transistor 1 in series. The potential difference across the resistor 101, that is, the voltage drop caused by the current (hereinafter referred to as the output current) flowing through the output transistor 1 is compared between the differential amplifier 103 and the reference voltage 102. The reference voltage 102 The comparison result of the differential amplifier 103, which is set to be equal to the voltage drop generated by the output current of the control target amount, is output to the control circuit. If the output current is larger than the control target amount, that is, when the output of the differential amplifier 16 is negative, the control circuit will block the output transistor 1 * The output transistor that is temporarily blocked will be held by the control circuit Its status. When the control circuit inputs a signal indicating conduction from the outside, or when the output of the differential amplifier 103 becomes positive after a predetermined time, the output transistor 1 will be turned on again, so that the output current is essentially Does not exceed the control target amount. However, as shown in the conventional example in FIG. 13, the resistor 101 is connected in series to the output transistor 1. Therefore, the range of the output voltage is reduced, or there is a problem related to excessive power consumption. 4 This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) A7 B7 V. Description of the invention (2) 丨 4 Picture shows the modification of the faithful circuit The current of the auxiliary transistor 2 is measured in series with the auxiliary transistor 2 and the resistance is 10 ohms. The output current of the auxiliary transistor 2 (hereinafter, referred to as the adjustment current is the output transistor for common input) The output current η rounded is only a small ratio. For example, in the case of integrated circuits, where the output transistor 1 and the auxiliary transistor 2 are integrated into a single piece, the auxiliary transistor 2 = the output transistor 1 is In fact, f is the same structure, but its size is smaller than that of wheel-out ss body 1. In this case, the ratio of the common input voltage and the current output by each transistor is essentially its size ratio. The electric current detection resistor 1 is used to control the withering current in the same manner as in the first conventional example so that it does not exceed the control target value. If the voltage drop ratio due to the resistor 101 is input in Output transistor] voltage is small enough to At that time, that is, the current ratio (Π / Ι2) is substantially equal to the size ratio of the transistor. That is, the current (Π) and (12) are proportional and the proportionality coefficient is based on the transistor on the solid shell. The size ratio is determined, and the output current (II) can be controlled so that it does not exceed the inverse of the above-mentioned control target quantity, which does not substantially depend on the input voltage and the temperature of the environment. In the case of the conventional example of the second item, the resistor [0] is not connected in series with the output transistor i. Therefore, it can make the voltage of the wheel output smaller than the original conventional example. The range can be expanded. At the same time, power consumption can be suppressed. If the voltage drop in two lifetimes is less than eight, in the output transistor!

Description of the invention (3) The voltage between electrodes (hereinafter referred to as the "gate voltage") is larger than that of the auxiliary transistor 2 The amount of voltage drop due to 101. Therefore, the ratio (n / I2) of the output current (n) to the adjustment current (12) is not only the size ratio of the transistor, but also depends on the source-drain voltage Or gate voltage and threshold voltage threshold parameters. Because of this, the output current (11) and the adjustment current (12) generally have a non-linear relationship. In particular, the output current (π) is easier to adjust than Use the current (12) to exceed the ratio determined by the size ratio of the transistor, and in the field with a larger interrogator voltage, 'make the current ratio (〗 丨 / Π) become several times larger than the size ratio of the transistor Fig. 16A is a graph showing changes in the output current (II) and the adjustment current (12) of the gate voltage of the transistor 1 in the conventional example of item 2. However, 'the vertical direction of the figure The axis is standardized for the purpose of making it easy to see the deviation from the proportional relationship. That is, when the curve corresponding to the output current (II) matches the curve corresponding to the adjustment current (12), that is, the output current (I1) and the adjustment current (12) have a proportional relationship. As shown in 16A®, in the conventional example of item 2, the output current (Π) and the adjustment current (12) are inconsistent especially in the area where the gate voltage is large. In addition, the deviation of the above two curves varies greatly due to the temperature variation of the threshold value of the gate voltage. If so, the current ratio (I1 / 12) varies depending on the gate voltage or temperature. Therefore, although the adjustment current (12) is controlled to be consistent with the predetermined control target value, the output current (I1) It will also change from the set value. Therefore, the conventional example in item 2 cannot improve the control accuracy of the output current (II) sufficiently, and it cannot ensure sufficient reliability. Fig. 15 is a conventional example of the third item of the interruption circuit.

Description of Invention (4)-The same as in the example of item With the output transistor 1 and the auxiliary transistor 2 connected in parallel, the conventional example of the third item is different from the conventional example of the second item, that is, the key of "transmission-electrical preparation". Lu. .Jingshizhi, to do the "very expensive .." is the same,.: Α, even the source voltage is different: especially in the output transistor 1, the voltage between the drain and the source is due to the load 3 The resulting voltage drop is easier to reduce significantly. Fig. 16B is a conventional example in item 3, and is a graph showing changes in the output current ΠΠ and the adjustment current (12) for the gate voltage. The vertical axis of Figure 16B is normalized in the same way as Figure 6A. As shown in Fig. 68, in the conventional example of item 3, when the gate voltage reaches a certain level, the output current (11) and the trimming current (12) will not match. In particular, the output current (I) changes with saturation as the gate voltage increases. As the conventional example in item 3, the current ratio (11/12) also varies depending on the gate voltage. Therefore, as in the conventional example in item 2, it is impossible to make the current out of the wheel (〖丨 丨) The control accuracy is fully improved. The conventional example in the second item 'because the gate voltages of the output transistor 1 and the auxiliary transistor 2 are different, and the conventional example in the third item is because the voltage between the drain and the source is different, The ratio (II / 12) of the output current (11) and the adjustment current (12) is caused to depend on various variation factors. Therefore, the present invention provides a control to make the output transistors 丨 and the potentials of the corresponding three terminals (gate, source, and drain) of the auxiliary transistor 2 consistent, so that the output current (Ϊ1) and the adjustment current (12) The ratio (11/12) is compensated for a certain output control device. Because of this 'the control accuracy of the output does not depend on variations in operating conditions or temperature or variations in dimensional ratios due to manufacturing errors', it is a device that has improved reliability than conventional ones.

The potential difference between the node ρ and the node q returned by the amplifier 4 is based on ', so that the equivalent impedance between the drain and source is changed and the potential difference between the node P and the node Q is adjusted to zero, so that the voltage The bridge is balanced. 6 The drain potential and the ytterbium potential of the output transistor 1 and the auxiliary transistor 2 can be understood from the structure shown in FIG. 1 and are substantially equal to each other. Therefore, as described above, the potentials of the three terminals of the two transistors are substantially equal to each other in a state where the bridge is balanced. In this case, the ratio (II / 12) of the source current of the two transistors is kept at a certain value η. Because of this, the source current of the transistor 2 will be subsidized while maintaining the balance of the bridge, that is, as long as the adjustment current 12 is controlled to a predetermined target value, the output of the transistor 1 can be made. The source current, that is, the output current (11) can be controlled to be equal to η times its target value. The control of the adjustment current (12) is performed as follows: "The second differential amplifier paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). )

Description of the invention (30) Roadmap. Current source 1: As shown in the first figure, it is the one that will be simplified by a large number of components, and it contains a transistor 1, a resistor 1, a differential amplifier | g 12c, a reference calendar丨 2d = transistor 123 is an 11-channel M0SFET, and the adjustment current is input from the drain (12 ”resistor 12b is for the 11 differential amplifier 1 2 c connected to the source and ground terminals of the transistor Ua) The voltage drop between the two ends of the resistor 1 2 b and the reference voltage 12d ', and the source current is substantially controlled so that it is less than the reference voltage l2d, which is set as the source When the pole current is equal to the control target value (h), it is equivalent to the amount of voltage drop generated at both ends of the resistor ⑶. If so, the current source 12 keeps the adjustment current ⑼ to a substantially control target value (lt). On the 3A ,, the control circuit 13 is 0N_0FF according to the input from the differential amplifier 4 or the external Η, and the voltage of the control power source 15 is intended to be transmitted to the gate of the output transistor 1 and the auxiliary transistor 2 or Switching (switching) circuit for pre-breaking. The voltage of control power source 5 The resistor 丨 6 a and the resistor 16 b divide the voltage, so that the output transistor 丨 and the auxiliary transistor 2 are required to turn on the sufficient gate voltage. The diode 17 is grounded at the anode and the cathode is connected At the node P. According to the above structure, the operation of the third embodiment is as follows. If the gate potential is constant, that is, 'the lower the potential of the node p, the output transistor 丨 will output a larger output current (丨丨).

Description of the invention (31) OFF. At this time, the adjustment current is maintained at the control target value (It) according to the current source 12, and the potential of the node p at the node Q is maintained. Nai The above-mentioned valley lower limit value is high, and therefore, the wheel-out current (Π) is substantially equal to or less than the value ηχ lt when the potential difference between the node P and the node Q is 0 (zero). On the other hand, the differential amplifier 4 When the output is less than the above-mentioned threshold value, that is, when the potential of the node P to the node Q does not reach the above-mentioned allowable lower limit value, the control circuit 13 is turned off regardless of the input from the external 14. The potentials of the respective gates are reduced, so the output transistor and the auxiliary transistor 2 are interrupted. Because of this, the allowable lower limit value for the potential difference between the node p and the node Q is set to correspond to the output current (11) The allowable upper limit value can protect circuit components from overcurrent. Furthermore, when the load 3 has an inductive reactance, the load current (II) flowing through the load 3 can be controlled as described below so that the control target value (11 X It) does not exceed a substantially predetermined control range (ΛΙ1). And get bigger. First, set the allowable lower limit value of the potential difference between the node P and the node Q to a slightly negative value so that the output current (Π) corresponds to a value (ΔΙ1) larger than the control target value (nx It). . When the output current (II) increases from the control target value (nx It) to (ΔΙ1), since the potential difference ratio between the node P and the node Q is lowered, the control circuit 13 is turned off. The output transistor 1 and the auxiliary transistor 2 are turned off. If it is, the output current (I1) decreases sharply to 0 (zero), but the load current (1) continues to flow through the diode 17, and gradually decreases according to the inductive reactance of the load 3. Therefore, before the load current (IL) has become too small, the control circuit 13 is turned on according to the input from the external 14 and the output of the paper is adapted to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). ) 34 Ί; " i ------- Order ---- (please read the note on the back before filling this page)

The switching (switching) control circuit 21 controls the gate potential of the switching transistor 18 according to the input from the differential amplifier 4, and controls the output current (I 丨) from it. Specifically, when the potential of the node p to the node q increases in the positive direction, that is, the switching control circuit 21 increases the gate potential of the switching transistor 8 and increases the output current (11).

In other words, the output transistor 1, the load 3, and the exchange The transistor 18, the auxiliary transistor 2, and the current source 12v are regarded as an electric bridge, that is, the switching transistor 18 is based on the potential difference between the node p and the node q which are feedbacked by the differential amplifier 4, and the drain The equivalent impedance between the sources is changed so that the potential difference between the node P and the node Q is adjusted to 0 (zero), that is, the bridge is balanced. The drain potentials of the output transistor 1 and the auxiliary transistor 2 As shown in Figure 5A 圏, the gate potential is substantially equal to each other. Therefore, as described above, in the state where the bridge is balanced, the potentials at the three terminals of the two transistors are substantially Equal. In this case, the output current (] 1) and the adjustment The ratio (11/12) of the current (12) is maintained at a certain value n. When the bridge is kept in a balanced state 'because of the current source] 2 ν is to control the adjustment current (12) to the control target value (It), so the output current (I1) can be controlled so that it is equal to η times its control target value (It).

On the other hand, the output of the differential amplifier 4 is the case where the above-mentioned threshold is not full, that is, the node The potential of p to node q does not reach the above combination. In the case of the lower limit of noon, the control circuit 2 is turned off, and the switching crystal 18 is turned off, so that the output current (I) is interrupted. Because of this, the allowable lower limit value of the potential difference between the node p and the node Q is set to correspond to the allowable upper limit value of the output current (II). Fp can protect the circuit elements from overcurrent. D Switch control circuit 21 As described above, the switching transistor 18 is controlled by analogy. However, in other cases where the load 3 has an inductive reactance, the switching control circuit 21 performs the switching control of the switching transistor 18 as described below to substantially balance the bridge. Firstly, the allowable lower limit value of the potential difference between the node P and the node Q is set to a small negative value and corresponds to the output current (Π) ratio (nx it) which is only a value of a large AH. occasion.

When the voltage of the DC power source 10 is applied to the load 3 again to increase the potential of the node P, the output current is caused by the reactance of the load 3 (II) Slowly increase and the potential of node P decreases again with it. Repeat the above actions As a result, that is, the output current (I i) does not substantially increase to a self-control target value (nx It) exceeding Λ1. Furthermore, by adjusting the time when the switching transistor 18 is turned off, the output current (11) can be reduced. The time average value is consistent with the control target value (nx It) »For the control of the output current (I 1) as described above, it is not necessary to insert the current detection resistor in the main arm containing the output transistor 1 and the load 3, Therefore, the range (dynamic range) of the output voltage can be made wider than that of the first conventional example in which the resistor is inserted. Moreover, it is different from the second conventional example in that it makes the output transistor 1 It is controlled with the auxiliary transistor 2 so that the potentials of the three terminals are maintained in common. Therefore, the ratio (I UI2) of the output current (Π) to the adjustment current (12) does not actually depend on the temperature and the three terminals. The potential is constant. Because it is different from the conventional one, the temperature change and the potential change of the three terminals will not reduce the control precision of the output. The above description 'Yu Bu Between the time when transistor 2 is ON, the current source 12 keeps the adjustment current (12) constant. However, it is maintained for a certain period of time ', which is the degree of the switching cycle when the output transistor I is turned ON-OFF as described above. In other words, since the reference voltage of the current source 12v is changed more slowly than the above-mentioned exchange cycle, the control target value (It) of the adjustment current (12) can be changed slowly and can be used by it. The control target value (nx It) of the output current (H) is also changed. 40 This paper size applies the national standard (CNS) A4 size (210 * 297 mm).

Invention Description (39 ) / And the source and source contain parasitic resistance, respectively. The output current of the output transistor 1 is usually extremely large. Therefore, the voltage drop due to the above-mentioned parasitic resistance is higher than the voltage applied to the transistor 1 in the wheel, and generally cannot be ignored. The parasitic resistance contained in the output transistor 1 must exist in the structure of the output transistor 1 and cannot be completely removed. Because of this, the above voltage drop will have an error that cannot be ignored for the ratio (Ϊ1 / Ι2) of the output current (II) to the adjustment current (12). Therefore, the resistor (113) and the resistor (114) are connected to the drain and source of the auxiliary transistor 2 as shown in the figure. Here, the resistor (R3) 'connected to the end of the auxiliary transistor 2 and the resistor (R4) connected to the source of the auxiliary transistor 2 are respectively set to be connected to the drain of the output transistor 1. Η times the resistor (R1) and η times the resistor (R2) connected to the source of the output transistor 1.
